WaPo: More than one in 100 adults in the United States is in jail or prison, an all-time high that is costing state governments nearly $50 billion a year and the federal government $5 billion more, according to a report released yesterday.

With more than 2.3 million people behind bars, the United States leads the world in both the number and percentage of residents it incarcerates, leaving far-more-populous China a distant second, according to a study by the nonpartisan Pew Center on the States.

The growth in prison population is largely because of tougher state and federal sentencing imposed since the mid-1980s. Minorities have been particularly affected: One in nine black men ages 20 to 34 is behind bars. For black women ages 35 to 39, the figure is one in 100, compared with one in 355 for white women in the same age group.

I'm not sure why prisoners are not put to work so that prisons could become self-sustaining. Is it crueler to warehouse people, or crueler to give them something to do?
